Abstract

The adsorption of tartrazine dye on active carbon of mahagony (Swietenia mahagoni Jacq) rind has been done. Through acquired active carbon carbonations process, where was that rind at entry into furnace on temperature 500oC for 1 hour, afterwards is cooled and sieved to 50 mesh. Activation process was done through charcoal soaking in 4 M HCl solution for 15 hours and be dried on ovens at 110o C for 1 hour. After that, by the calcinations process in furnace at 450o C was streamed to gas N2 for 2 hours then analysed by X-ray diffraction (XRD) to charcoal before activation, after activation and after calcinations. Adsorption process to tartrazina dye utilize UV-Vis spectrophotometer was been done. Result of research are gotten optimum condition of active carbon which is on adsorben’s weight 1.0 g, contact time 40 minutes, pH = 3 and concentration of tartrazine dye on 30 ppm. Adsorption of tartrazine dye on the active carbon fits Freundlich's isotherm at the value correlation coefficient (r 2 ), value K F , and value n which is 98%; 0.015 and 1.186 respectively.

Abstract

Sagoo plant (Metroxylon sp.) numerous in eastern Indonesia, such as Maluku and Papua. Sagoo starch containing amylose and amylopectin. Sagoo starch hydrolysis can be carried out by enzymes, such as glucoamylase or often called amiloglukosidase or α-1 ,4-glukanoglukohidrolase, an extracellular enzyme capable hydrolyzes α-1, 4 on amylose and α-1, 6 in amylopectin. The enzymatic hydrolysis of starch can be reviewed in the kinetics of the Michaelis-Menten equation and Lineweaver-Burk equation. The aims of this study to determine the kinetic parameters (Vmax and Km) of glucoamylase on hydrolysis of sagoo starch. Glucoamylase has an optimum temperature of 50 oC and pH optimum 6.5. At optimum conditions, based on Michaelis-Menten equation, the value of Vmax is 1.09 U/mL/min and Km value is 0.82. Based on Lineweaver-Burk equation, the value of Vmax was 1.03 U/ mL/min and Km value was 0.84%.

Abstract

An extraction of chitin from shell of the tiger shrimp (Penaeus monodon), a convertion chitin into chitosan and depolymerization chitosan into oligochitosan using hydrogen peroxide based on variations in heating temperature have been done. Chitosan had depolymerized and it’s molecular weight had tested by end group analysis method and it’s degree of deacetylation had tested by UV-Vis spectrophotometry method. Oligochitosan had obtained from the conversion of chitin is isolated from the shell of tiger shrimp and from commercial chitin. The content of chitin obtained in tiger shrimp shells was 35.90% while the result of the conversion of commercial chitin into chitosan amounted to 62.33%. Characterization of functional groups using FTIR spectrophotometry showed that the conversion of chitosan from chitin commercial have absorption bands of 3617.56 (OH), 3050.47 - 3127.63 (-NH stretching), 2894.24 (-CH methylene), 1679.06 (-C = O), 1564.30 (-NH bending), and 1076.30 cm-1 (-CO-). The commercial chitosan which is characterized by FTIR spectrophotometric method also supports the results of the conversion of chitosan from chitin commercial. In the process of depolymerization of chitosan by hydrogen peroxide was found that the greater heating temperature was used, the smaller the percent yield and molecular weight of oligochitosan were at 40 oC, 50 oC, 60 oC and 70 oC gained weight average molecular oligochitosan were 1030.12 g/mol, 1019, 28 g/mol, 978.12 g/mol, and 908.82 g/mol, respectively

Abstract

The research of carbon characterization from candlenut shells before and after activation has been done. Activated carbon were obtained through the heating process at 350 °C for 2 hours. The carbon charcoal were further cooled and sieved with a 100 mesh sieve. Then, calcinated at 450 °C and nitrogen (N2) were flowed for 2 hours and characterized by XRD for carbon before activation. Carbon was activated by using KOH solution with a concentration of 50% for 5 hours, then dried in an oven at 120 °C for 1 hour and characterized. XRD diffractogram of crystallization for carbon before activation produced three main peak were 2.93 Å, 3.25 Å, and 8.26 Å, and at 2Ө region of 30.47°, 27.40°, and 10.70°, respectively. XRD diffractogram of crystallization for activated carbon produced three main peak were 3.0195 Å, 3.3383 Å and 8.0955 Å, the 2Ө value which was shifted of 29.560°, 26.682°, and 10.920°. This shift indicates that the distance difference between charcoal crystal face caused by KOH activator. Weight acidity solids before and after activation was 27.370 x10-3 and 33.1245x10-3 mol.g-1, respectively.

Abstract

The chitosan isolation from crab crab waste (Portunus sanginolentus) has been carried out. Chitin production is carried out by the de-proteination, demineralization and depigmentation processes. Chitosan biopolymer is produced from chitin through de-acetylation method using base solution (NaOH) and the addition of NaBH4 which aims to increase the degree of de-acetylation (DD) of chitosan. The results of 25 g of chitin obtained chitosan amounted to 16.67 g (66.68%). Chitin and Chitosan were identified by a Fourier Transform Infrared (FT-IR) spectrophotometer.
